Description: 4-in-1 Portable Red Light Therapy Lamp, 120 LED Light Therapy, Red Light Therapy Lamp, Timer Mount, 660 nm, 850 nm 4 Dimming Modes + 5 Timing Modes + 5 Mode Switches Red light 660 nm improves skin elastin and brightness, reduces wrinkles and pigmentation, and stimulates skin metabolism; Infrared light 850 nm relieves pain, reduces dark spots, and stimulates circulation; Blue light 460 nm antibacterial, oil-regulating, and anti-inflammatory. Yellow light 595 nm relieves redness, erythema, and swelling Red light therapy principle: Red light therapy, also known as low-level laser therapy (LLLT) or photobiomodulation, is a technique that uses specific light wavelengths (usually between 400 nm and 1000 nm) to increase cell function and repair, reduce inflammation, and relieve pain. Its principle of action is primarily based on the process by which light energy is absorbed by the cell and converted into biological energy, stimulating the cell's natural repair and regeneration mechanisms. The LED light therapy panel combines different spectra of 460 nm, 660 nm, 595 nm, and 850 nm to penetrate deep into the tissue. Light penetrates deep into the tissue, activates cells, and promotes metabolism. It stimulates collagen growth, improves blood circulation, and regulates the nervous system of the head. Main functions: Improves blood circulation, accelerates metabolism, relieves fatigue and pain, and supports wound healing.
